摘　　要：客滚船车辆甲板强横梁和纵桁的强度、刚度一般由直接计算方法分析校核,梁系模型和有限元模型是最常使用的2种直接计算模型。利用以上2种模型对车辆甲板典型门式钢架结构进行建模,对比分析其在均布载荷作用下的静力响应,结果显示钢架端部无肘板交叉连接处剪应力存在较大差异,分析差异原因并回归了该位置梁系模型和有限元模型剪应力的换算关系,使梁系模型计算结果更接近有限元分析结果,提高初步设计阶段车辆甲板主要支撑构件的设计精度。Design and evaluation of a Ro/Ro passenger ship’s vehicle deck primary structural members are generally carried by direct calculation method. The beam model and finite element model are the two most commonly accepted by classification societies. By comparing the results of beam model and the finite element model for a typical portal frame of Ro/Ro passenger ship, shear stress in beam-to-column connection is corrected to make the results of beam model closer to that of the finite element model which could make the structure more reliable at preliminary design stage.
